What is a SMS QR Code?
An SMS QR code encodes an SMS URI containing a phone number and optional pre-filled message body. When scanned, the device opens the native Messages app with the recipient number and message ready to send — without the user needing to type anything. This is the most effective way to drive opt-ins for SMS marketing programmes from physical materials.

Best practices for sms qr codes
Pre-fill a keyword for opt-in compliance
For marketing programmes, pre-fill the message body with your opt-in keyword (e.g. 'JOIN' or 'YES'). This creates an auditable consent record without the user having to type anything.
Include the country code in the phone number
Always format the number with country code (e.g. +44 for UK, +1 for US). Without it, the QR code will only work for users whose device is on the same country network.
Keep the pre-filled message under 160 characters
Standard SMS messages are 160 characters. If the pre-filled text exceeds this, it will be sent as a concatenated multi-part message which may cost the sender more or appear split on older devices.
